    [0002] Mechanical lock for community doors
    [0003]
    [0004] TECHNICAL FIELD
    [0005]
    [0006] The present invention relates to a latch lock without slip, of the type used in doors for common areas of neighborhood communities, portals, urbanizations, shared spaces or offices, which has a simplified mechanism consisting of three parts through which you can The latch can be operated both with a handle located on the inside of the door and with a key that can be inserted on both sides of the door.
    [0007]
    [0008] BACKGROUND OF THE INVENTION.
    [0009]
    [0010] Several models of locks are known to be installed in portals and common areas of neighborhood communities, which are characterized by not having slip, but only involve a latch that is retracted by a handle or a key.
    [0011]
    [0012] This type of lock is used in combination with keyholes pivoting or sliding, which allow the entry and exit of the latch without the need for retraction.
    [0013]
    [0014] Examples of this type of locks is described in patent P201731330.
    [0015]
    [0016] This type of locks fulfills its function in an optimal way, however, they are constituted by a large number of pieces, resulting in complex, usually bulky and high cost mechanisms that require doors with wide areas for installation, which prevents their installation in small doors and minimalist design.
    [0017]
    [0018] Therefore, it would be beneficial to develop a single latch lock operable from a handle or through a key, consisting of a small number of pieces, which would allow a significant reduction in size and which consequently could be sold at lower prices.
    [0019]
    [0020] DESCRIPTION OF THE INVENTION
    [0021]
    [0022] The present invention refers to a mechanical lock for doors of communities that solves the problematic exposed since its mechanism is composed of only three pieces of very simple fabrication and assembly, reason why its cost is objectively inferior to the one of the conventional locks and, at the same time allowing an important
    [0023] Volume reduction, which facilitates the development of more simple and stylized design doors.
    [0024]
    [0025] In particular, the novel lock is constituted by a mechanism formed by a rotor with three radial arms that moves a piece of retraction of the latch and a piece of blocking of the piece of retraction of the latch.
    [0026]
    [0027] The rotor has a first arm on which an eccentric is associated with the axis of the inner handle of the lock, so that, when the handle is operated, the rotor also rotates.
    [0028] The retractable part of the latch has a flat horizontal configuration and moves on a horizontal slide made in the lock box, remaining in the position of latch extended by the action of a spring whose force has to be overcome to move the piece towards the opposite side of the slide, corresponding to the retracted latch position.
    [0029]
    [0030] The retractable part of the latch has a superior and inferior profile of differentiated design.
    [0031]
    [0032] The upper profile presents a silhouette with a vertical protrusion on which the third arm of the rotor impinges, which, when turning, propels the piece towards the opposite side of the horizontal slide, overcoming the force of the spring, with which the retraction occurs. of the latch, which is in solidarity with this piece.
    [0033]
    [0034] The lower profile has a silhouette with a notch in which fits the cam of a safety bulb that is attached to the lock box. In its turning movement, the cam meshes with the notch and urges the retraction part of the latch towards the opposite side of the horizontal slide, overcoming the force of the spring, with which the retraction of the latch also occurs.
    [0035]
    [0036] The function of the blocking piece is to immobilize the retraction part of the latch, preventing its retraction, even if it is forced from the outside.
    [0037]
    [0038] This piece has a vertical flat configuration overlapping the retraction part of the latch and incorporates vertical slides through which pivots pass integral to the lock box, so that it can move up or down inside it, staying in the latch position blocked by the action of a spring whose force has to be overcome to move the piece towards the opposite side of the slide, corresponding to the released latch position.
    [0039] The central area of this piece undergoes a widening projecting towards the latch, in which an irregular slider is arranged through which a protruding locking pivot of the retraction part of the bolt runs.
    [0040]
    [0041] In said slide two parts are distinguished, a narrow upper zone in which it fits with precision the pivot of blockade, so that when this this located in this zone, the movement of the piece of retraction of the latch is disabled and a wide area lower by which the locking pivot can move freely so that the retraction part of the latch is released.
    [0042]
    [0043] The upper end of the blocking part has a horizontal protrusion on which the second arm of the rotor strikes, which, when rotated, moves the blocking piece upwards along its vertical slide and overcoming the force of the spring, thereby the locking pivot that was located in the upper narrow zone of the irregular slide passes to the lower wide area, releasing the retraction part of the latch.
    [0044]
    [0045] The lower profile of the central widening of the blocking part has a silhouette with a rounded corner at its end on which the cam of the safety bulb impinges, which when making its turning movement moves the blocking piece upwards, as length of its vertical slide and overcoming the force of the spring, so that the locking pivot that was located in the upper narrow area of the irregular slide passes to the lower wide area, releasing the retraction part of the latch.
    [0046]

    [0093] DESCRIPTION OF A PREFERRED EMBODIMENT
    [0094]
    [0095] The new mechanical lock for doors of communities a mechanism formed by a rotor (1) that moves a piece of retraction of the latch (2) and a blocking piece (3) of the piece of retraction of the latch (2).
    [0096]
    [0097] The rotor (1) has a first arm (4) on which an eccentric (7) associated with the axis of the lever (8).
    [0098]
    [0099] The retraction part of the latch (2) moves on a horizontal slide (9) made in the lock box (10), advancing or retracting inside it and its upper profile has a vertical protrusion (12) on the which affects the third arm of the rotor (6) that rotates the impeller and moves through the horizontal slide (9), which results in the retraction of the latch (13). On the other hand, its lower profile has a notch (14) in which the cam (15) of a safety bulb (16) engages which, in its turning movement, also drives and displaces the retraction part of the latch (1). ) by the horizontal slide (9), which also results in the retraction of the latch (13).
    [0100] The blocking piece (3) incorporates vertical slides (17) through which pass through pivots (18) integral with the lock box (10) that allow it to ascend or descend inside it and its central area experiences a widening (20) in which there is an irregular slider (21) through which runs a blocking pivot (22) protruding from the retraction part of the latch (2) and in which a narrow upper zone (23) is distinguished in which the locking pivot (22) can be inserted, the movement of the retraction part of the latch (2) and a wide lower zone (24) by which the locking pivot can move freely so that the retraction part can be prevented. of the latch (2) is released.
    [0101]
    [0102] The upper end of the blocking part (3) has a horizontal protrusion (19) in which the second arm of the rotor (5) strikes, which rotates the impeller and moves upwards through the vertical slide (17) so that the pivot lock (22) that moves through the Irregular slider (21) passes from the upper narrow zone (23) to the lower wide zone (24), releasing the movement of the retraction part of the latch (2).
    [0103]
    [0104] The lower profile of the widening (20) of the blocking part (3) has a rounded corner (11) on which the cam (15) of the safety cylinder (16) strikes, which, in its turning movement, also drives and the locking part (3) moves upwards so that the locking pivot (22) also passes from the upper narrow zone (23) to the lower wide area (24), releasing the movement of the latch retraction part ( two).
    [0105] The operation of the device is as follows:
    [0106]
    [0107] In rest position, by means of springs not illustrated, the latch (13) of the lock is extended, the retracted part of the bolt (2) is blocked and the blocking piece (3) located in its lowest position immobilizing the locking pivot (22).
    [0108] Starting from that position, the retraction of the latch (13) can be done in two ways, through the inner handle of the lock or through the key inserted in the safety bulb (16).
    [0109]
    [0110] If the actuation is carried out by means of the handle, the rotor (1), the upper profile of the retraction part of the latch (2) and the upper end of the blocking part (3) come into action.
    [0111]
    [0112] When turning the lever, the eccentric (7) associated with the axis of the lever (8) hits the first arm of the rotor (4) and makes it turn (figure 6). When starting to turn, the second arm of the rotor (5) hits the lower face of the horizontal protrusion (19) present in the upper part of the blocking piece (3), moving it upwards, so that the locking pivot (22) goes from being fitted in the upper narrow zone (23) of the irregular slider (21) to the lower wide zone (24) thereof, releasing the retraction part of the latch (2) (figure 7).
    [0113] By increasing the rotation of the lever, the third arm of the rotor (6) comes into contact with the vertical protrusion (12) of the retraction part of the bolt (2) and moves it along the horizontal slide (9) so that the latch (13) is retracted into the interior of the lock box (10) (figure 8).
    [0114]
    [0115] If the drive is carried out with a key inserted in the safety bulb (16), the cam (15), the lower profile of the retraction part of the bolt (2) and the lower profile of the widening of the work piece come into action. blockage (3).
    [0116]
    [0117] By turning the key, the cam (15) of the safety bulb (16) rotates until it meets the rounded corner (11) of the blocking piece (figure 9).
    [0118]
    [0119] As the rotation continues, the cam (15) moves the locking part (3) upwards so that the locking pivot (22) goes from being fitted in the upper narrow zone (23) of the irregular slider (21) to the lower wide area (24) of this, releasing the retraction part of the latch (2). At the same time, the cam (15) reaches the recess of the recess (14) (Figure 10) and engages it, so that, as the turn continues, it moves the retraction part of the latch (2) by the horizontal slide (9) with which the latch (13) is retracted into the interior of the lock box (10) (figure 11).
